Application filed November To all-107mm it may concern:

Beitlmownthatl,Jenn ll LlVRIGI-XT, a citi Zen of the United States oi.America residing at Birmingham, in the county of Jefferson and State of Alabama, have invented certain new and useful Improvements in Frostproof Flush Drain and Supply Valves, of which the following is a specification.

My invention relates to frost-proof drain and supply valves for closets, hydrants, street washers and the like.

lit is characteristic of my invention in its various forms, that the valve stem shall project upwardly through the valve body and carry loosely on a "squared lower portion thereof an inverted valve seal; which, turning with the valve stem, can be screwed into and seated tight against a seat in the lower part of the valve body. A supply valve which is adapted to close with the pressure is carried by the valve stem which is guided in its verticalmovements by a spider guide in the removable supply valve seat. By th s arrangement the entire valve mechanism can be readily unscrewed and removed fromthe valve body, and after being repaired can be placedwithout disturbing the valve body the seat and valve being removable by turning the upper end of the valve stem which isfconvenien'tly accessible.

A further object of my invention is to hang the valve looselyon the lower end of the valve, stem so that it will close tight whether or not the seat is true.

"A further object of my invention as designed for the pressure tank and frost-proof closets is that the water pressure Wlll co-act withjthe valveseating spring to raise the closet seatthereby enabling a smaller and lighter spring to be employed. Moreover, by arranging the spring in a chamber at the top of the compound valve body and providing a packing or stuiiing boxto protect the spring chamber from access of water, I protect the spring firom wat er and by packing the spring in grease its life can be indefinitely prolonged. A further object of my invention is to adaptthe valve to be removed for repairs without having to do anything but detach a sleeve nut at the top of the valve body and apply a wrench to the spring chamber which turns with it the valvestem to unscrew the seat.

A further object is to make the drain valve out of flat washers carried by a spider ad- 24, 1919. Serial No. 340,135.

justable on the valve stem, which stem can be readily lengthened or shortened by the provision between the drain and flush valves of anattachable section made or out to the desired length to properly space the said valves relatively.

It is further object to so design the parts that the whole valve mechanism can be taken apart with an ordinary wrench as no bolts orscrcws are used except in hydrants.

My invention further comprises the novel details of construction and arrangements of parts, which are more particularly described and claimed in their preferred embodiments only in the accompanying drawings, in

which V Fig. 1 shows in side elevation a frostproof closet equipped with my valve mechanism.

Figs. 7 and 8 are viewscorresponding to Fig. l. of modifications of my invention as applied to a pressure tank closet and a frostproof hydrant, respectively.

Similar reference numerals refer to similar parts throughout the drawings.

As illustrated in Figs. 1 and 2, I show an ordinary type of frost-proof closet comprising a water supply pipe 1 connected to the lower valve bodv 2, which is connected by a pipe 3 to the upper valve body 4. This lattervalve body is connected by a pipe 3? to the pressure tank 3? overhead and by a flush pipe 5 to the bowl 6. The upper valve body l is provided withbrackct. arms 7 to which the hinge fittings S of the closet seat 9 are pivoted so as to overhang the valve body.

The valve mechanism comprises an inverted. seat 10 formed preferably as an integral part or the rim ll of the spider 12, the hub 13 01" which is provided with a square hole through which a square valve stem 14 passes looselr and has its lower end keyed in a. sleeve 15 which has its bottom end contracted so as to hold the ball 16 on a hanger rod 17 which carries the supply valve formed by a flat non-metallic washer A washer 22 is mounted around the upper end of the valve seat at its point of juncture with the threaded rim 11 of the spider, the washer being mounted in a countersunk groove in the rim so as to be removable therewith. The valve body is provided with a seat 23 at the base of its threaded portion 24 into which the rim 11 screws and the washer 22 thus serves to insure a tight joint between the seat 23 and rim 11, and the washer being removable with the rim can be readily replaced. The upper end of the stem 14 is socketed to receive a square connecting rod 25 which is keyed in the socket of the stem 14 and at its upper end is keyed into the socket of a depending central boss 26 preferably formed integral with the metallic flush-valve retainer 27. The boss 26 is threadedto receive a nut 28 which holds the flat washer valve 29 in position on the underiace of the retainer 27 and this washer is adapted to engage a seat 30 in the valve body 4. The retainer 27 at its upper end is provided with a squared socket into which the lower end of a square spring rod 31 is inserted and keyed,the top end of said rod being threaded and screwed into the upper invertecl telescoping sleeve 32 of the spring chamber. This sleeve telescopes over a lower sleeve 33 which is integral with a body portion 34 having flattened faces to form a wrench grip and is also integral with a fiange35 adapted to rest on a washer 36 on thet'op of the valve body 4. The lower end of the "sleeve 33 is closed except for a square hole through which the spring rod 31 slides, and a spring 37 surrounding the rod in the spring chamber bears at its upper end against the sleeve 32 and at its lower end against a metallic washer 38 between which and the bottom of the sleeve member 33 is introduced packing to rorm a stuiiing box 39 that will prevent the leakage of water from the valve body 4 into the spring chamber, which, if desired, can be packed with grease. A screw cap 40 is adapted to screw onto the top of the valve body 4 and to draw the flange 35 with a tight fit against the washer 36 and thus close the top or the valve body 4.

lVhere the fixture is of the frost-proof type, a small drain pipe 41 is arranged in the lower valve body 2 just above the supply valve and this connects to the sewer system and-serves to drain off the water remaining in the valve body afterthe supply valve 18 is closed. In order to prevent the leakage of water through this drain valve while the supply valve is open, I mount on the valve stem 14 a valve formed by one or more nonmetallic washers 42 which are mounted on the rim of a spider 43 that can be set at any desired adjustment on the stem 14 by means of the set screw 44. A nut 45, screwed on the rim ot the spider, holds the washers in place and the washers form a valve adapted to close the drainv pipe41 when the supply valve is in open position.

The description as given applies equally to the pressure closet illustrated in Fig. 7, except that here the drain 41 is not required and the valve therefor is omitted. Here the valve body is short and formed as an in tegral casting thus omitting the pipe 3, it being unnecessary to place the supply valve in. the ground as in Figs. 1 and 2.

For the hydrants, the description of parts for the supply valve and its seat, the drain pipe and the drain valve are as already described, but where the compression type of valve operating mechanism is employed I provide the rod 46, corresponding to 25, with a square head 47 at its upper end which is received in a coupling box 48 opposite the joint between the faucet 49 and the coupling flange 50 at the top of the pipe 3. The box 48 is provided top and bottom with slots 51 through which the head on the rod 46 and a round head 53 on an operating rod 52 can be inserted into the coupling box. The rod 52 is screwed into a boss 54 on the faucet and passes through a stuliing box 55 and has on its upper end a handle 56. A set screw 57 is used to attach the box 48 to the head 47 on the valve stem 46. i

In assembling the valve mechanism the screw cap 40 is removed and the entire valve mechanism, as shown inFigs. 1 to 7, is lowered into the valve body until the threaded seat rim 11 engages the threaded section 24 of the valve body, after which a wrench is applied to the grip 34 and turned to screw the seat down. until the washer 22 is compressed between rim 11 and the valve body seat 23. The several valves, before being thus introduced into tliebody, are properly spaced on the valve stem so that when the valve 29 seats the valves 32 will close the drain 41 and when the supply valve 18 seats the valve 42 will open the drain 41. The screw cap 40 is then replaced and screwed down until it clamps thefiange 35 against the washer 36 to secure a tight top closure for the valve body 4. As thus arranged, the valves are operated by the depression of the seat 9 and by the counteraction of the spring 37 and the water pressure on the supply valve 18. Then the seat is depressed, the top valve chamber sleeve 32 is forced downwardly carrying with it the spring rod 31, compressing the spring 37, seating the flush valve 29', closing the drain 41 and opening the supply valve 18. When the seat is released, the combined action of the spring and pressure on valve 18 will seat the latter valve and open the drain and open the flush valve. To remove the valve mechanism for inspection and repair, the screw cap 40 is taken off and all of the valve mechanism is lifted upwardly out of the valve bodies, after the supply valve seat has been unscrewed from the body.

In the case of the compression hydrant shown in Fig. 8, when the faucetis disconnected from the collar 50, the former is shifted to disconnect the rod 52 from the coupling box. 48, after which a wrench is applied to the box 48 or to the head 47 and the latter is turned to unscrew the valve seat 10 from the body, thus permitting the valve mechanism to be lifted out, adjusted and replaced as has been already described.

This invention is not intended to be restricted in scope to the specific embodiments shown, but contemplates such modifications as come within the spirit and scope of the claims. i

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is v 1. In a valve mechanism of the character described, a valve body having a top opening and a lower inverted valve-seat screwed into the valve body and upwardly removable through said top opening, a valve stem carrying a valve for co-operating with said seat, and means on the stem to unscrew said inverted seat and remove it with its valve through the top opening of the valve body, said body having a removable top closure formed with a spring chamber through which said valve stem projects, said chamber having packing in the bottom and containing oil, a spring working in said chamber and tending to move the valve stem to seat said valve, and a telescoping cover for said chamber carried by the valve stem.

2. A valve mechanism in accordance with claim 1, in which said closure portion carrying the spring chamber is mounted by a screw collar on the valve body and is provided with a wrench grip and a squared opening for the valve stem, said valve stem being squared throughout the portion that is movable through said top closure.
